Consensus21 is a decentralised education protocol built to replace traditional schooling with community-governed, problem-based learning, no tuition debt, and no standardised tests. Learners from age 5 to 21 progress through real-world projects, manage their own schedules, build digital portfolios, and participate in governance alongside mentors, all within a system powered by Bitcoin for value, Nostr for identity, open-source tools and transparent, peer-driven innovation.
